well at least somebody said something now, but I still noticed something interesting
"Low 2-C | Universe level+: Characters who are capable of significantly affecting
[1], creating and/or destroying an area of space that is qualitatively larger than an infinitely-sized 3-dimensional space. Common fictional examples of spaces representing such sizes are
space-time continuums of a universal scale. However, it can be more generally fulfilled by any 4-dimensional space that is either:
A) Equivalent to a
large extra dimensional space. That is, a higher-dimensional "bulk" space which embeds lower-dimensional ones (Such as our universe) as subsets of itself, whose dimensions are not
microscopic / compactified."
in other words, it doesn't even need to be destruction of "the dimension of time" it can just be the destruction of multiple universe sized spaces to be low 2-C anyways
but even so, you forgot to include that they specify many times that the "entire" universe is being destroyed, which still would include time
and it's not like dragon ball is a verse that never acknowledges time cause yknow, zamasu stuff
timeline destruction is 4d, but an actual 4th dimension feat is also 4d
